A series of 2-aryl-3-(4,5,6-trimethylpyrimidin-2-yl) thiazolidin-4-ones ( – ) and their derivatives bearing a lipophilic substituent, like acetoxy group ( – ), propionyloxy group ( – ), methyl ( and ) at C-5 on thiazolidin-4-one ring were designed, synthesized and evaluated for their HIV-RT inhibitory activity. Using self-catalyzed Pummerer reaction, compounds – and – were obtained in good yield (63.1% 75.2%). Preliminary anti-HIV-RT test of these derivatives indicated that compounds – , (propionyloxy group at C-5) showed moderate HIV-RT inhibitory activity and compounds and with methyl at C-5 showed a weak HIV-RT inhibitory activity. Structure activity relationship analysis suggested that the substituted groups on C-5 would be unfavorable to anti-HIV-RT activity and that the steric effect might play a critical role in the anti-HIV RT activity.
